HORSESHOE-CALK.

Specification of Letters Patent.

Patented Nov. 10, 1914.

Application filed June 10, 1914.. seriaiivo. 844,299.

and adjustable therebetween whereby its effective ground engaging end may be projected to any desired distance below the.

lower ends of said relatively separable sections as the occasion may demand.

A further object of the invention is the provision of a calk of this character in which the core thereof will be adjustable and removable so that it may be readily separated from the shoe at any time and sharpened and the calk thereby maintained in'an active condition at all times.

Another object of the invention is the provision of a calk of this character which will be provided respectively at the opposite sides of the core with recesses which are adapted, in practice, to permit the calk end of the shoe to obtain eifective purchase against the ground and to minimize the possibility of the horse falling when moving over slippery surfaces.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrange ment of parts, as will be hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a bottom plan View of a horseshoe, showing heel and toe calks applied thereto and constructed in accordance with this specification; Fig. 2 is a section, taken on the line 2-2 of Fig. 1; Fig. 3 is a perspective view of a portion of the shoe, showing the removable calk sections thereof removed; Fig. 1 is a perspective view of the removable calk; Fig. 5 is a section on the.

line 55 of Fig. 1; and Fig. 6 is a view similar to Fig. 1, showing a slightly modified form of calk.

The shoe 1 shown in Fig. 1 is Identical in outline with any ordinary or well known form of shoe and at the heel ends the sidebranches of the shoe are provided with permanent calk sections 2 and removable calk sections 3. The removable calks are adjustable with relation to the immovable sections 2 by means of set screws 4 which are connected respectively with movable and immovable sections, as shown in Fig. 5.

Located between the sections 2 and 3 isa core 6 of steel and as shown the said core is provided with an integral lug 7 which has interchangeable connection with a vertical series of teeth 8 formed in the adjacent calk section 2. Through this arrangement it is obviously seen that. on adjusting the set screw 4, the sections 2 and 3 may be moved with such relation to each other that will cause the lugs 7 of the core 6 to be properly advanced into co-active engagement with the adjacent teeth 8 of the other section of the calk and as a consequence thereof the mentioned core 6 will be properly held in its adjusted position.

The lower edge of the calk is sharpened at 9, and as the core becomes dull the sections 2 and 3 of the calk may be separated relatively and the core may be removed and resharpened and then reinserted between the calk sections and the lugs 7 may be connected with an appropriate tooth 8 that may be necessary to a proper projection of the sharpened edge of the core below the extremities of the calk sections 2 and 3. This construction is desirable in that the sections of the calk may be separated expeditiously and the core sharpened and used for a large number of times. In order to increase the purchase of the core against the surface particularly when the horse is traveling over' slippery surfaces it is desired that the calk sections be provided with recesses or pockets 9, 9 respectively disposed at the opposite sides of the core as shown clearly in Fig. 1.

The toe calk shown in Fig. 1 is substantially identical with the form of heel calk and it is provided with an integral immovable section 10 and a removable section 11. Between the said sections 10 and 11 is adjustably mounted a core 12 which is substantially identical with the form of core 6 forming a part of the heel core. Excepting for the fact that the toe calk is provided 1 with recesses or pockets 1313 the said toe I sections of each calk be provided with lugs 14 that are adapted to engage in corresponding recesses in the shoe. This arrangement is found to give stability to the movable sections and to prevent the same from being accidentally broken when strain is applied thereto. As regards the toe calk it is also described that it is preferred to use two set screws 15, 15 for the purpose of securing both sections of the calk operatively assembled and properly connected with the core. The heads of the screws l and 15 are so located as shown in Fi g. 1 that they will not be exposed and they will be consequently held against being broken by the animal kicking his hoof against the ground.

I claim 1. A horse shoe provided with a calk having relatively adjustable sections, and a core adjustably mounted between said sections.

2. A. horse shoe provided with a calk hav ing relatively adjustable sections, one of the sections having a series of teeth, and a core adjustable between the sections and having a lug interchangeably connected with the teeth.

3. A horse shoe provided with a calk having relatively adjustable sections, one of the sections having a series of teeth, a core adjustable between the sections and having a lug interchangeably connected with the teeth, and means for moving the sections relatively to confine the lug of the core to its engaged tooth.

4. A horse shoe having a calk comprising a fixed section and a second section adjustable with relation to the fixed section, means for adjusting the sections relatively, and a core of hard metal interposed between both sections and provided with a sharpened edge underlying the lower edge of said sections.

5. A horse shoe having a calk comprising a fixed section and a second section adjustable with relation to the fixed section, means for adjusting the sections relatively, a core of hard metal interposed between both sections and provided with a sharpened edge underlying the lower edge of said sections, one of the said sections having recesses disposed respectively at one side of the core.

In testimony whereof I aflix my signature in presence of two witnesses.
